It is the responsibility of fathers to set the spiritual tone of His family. This obligation is not debatable and it is necessary. The fact that God gave men dominion over the earth means that men can speak things that will be received by others in a way that no one else can. The ears of children are tuned to their father’s voice. So he must accept the challenge of giving his children the power to live Godly lives in the earth by instructing them according to God’s word. The greatest commandment in Scripture is this: Love the LORD your God with all your heart and with all your soul and with all your strength Deuteronomy 6:5). Going back to verse 2, we read, So that you, your children and their children after them may fear the LORD your God as long as you live by keeping all his decrees and commands that I give you, and so that you may enjoy long life. Deuteronomy 6:5, we read, These commandments that I give you today are to be upon your hearts. Impress them on your children. Talk about them when you sit at home and when you walk along the road, when you lie down and when you get up (vv. 6-7).
